SPECIFICATION formi-ngpart of Letters Patent No. 60 1 ,934, dated April5, 18 98.

Applicationfiled April 14, 1896.

To all whom it may concern;

Be it known that I, 'MATTHIAS BROOK, of

Boston, county of Suffolk, State of-,- Massal chusetts, have invented anImprovement in Lasting-Machines, of which the following description, inconnection with the accompanying drawings, is a specification, likeletters and figures on the drawings representing like parts. v

In United States Letters Patent No; 548, 86 2,

granted to me under date of October 29,1895,

I have shown and described alasti'ng-machine wherein thewipers are madeto open and close to wipe the upper .over and upon the inner sole andare also connected with a cross-bar which is manually movable to varythe lateral position or adjustment of the wipers to adapt the same tolast ends of difierent inclinations or swing-such, for instance,as lastseither rights or lefts.

In this my present invention I have provided one form of vmeans'wherebythe wipers or lasting devicesand the last are automatically andrelatively adjustable to adapt said lasting devices or wipers to lastends having, different inclinationsthat is, a difference in swingwhetherthe lasts be rights or lefts.

Myinvention further comprehends means automatically and means manuallyforeffecting the relative adjustment of the said end Wipers and last tomeet the varying swing, of a last, whether a right or a left, the saidantomatic or the said manual means to be'employed by and at the will ofthe operator, according as automatic or manual means is desired.

Figure 1, in side elevation, represents the I head of a lasting-machineembodying my invention with the toe portion of a boot o'r shoe to belasted shownin operative position. Fig. 2 is a front elevation of theapparatus shown in Fig. l with the boot or shoe omitted. Fig. 3 is a topor plan view of the apparatus shown in Figs. 1 and 2, showing also aboot or shoe .2

in position to be lasted. Fig. 4 is a longitudinal sectional View of theoperative 'parts-of the head, taken on the line a: m, Fig. 3; and

Fig. 5 is an under side view of the cap for thetipping plate, with theside-wiper plates,

Serial No. 587,488. (No model.)

l their carriers, and the longitudinally-movable l slide-bar upon whichthey'are mounted.

Referring to the drawings, Figs.- 1 to 4, incl'usive, I have hereinshown a tipping-plate holder A, having upturned ends a a to formbearings for journals b'b, respectively, of a tipping plate B, wherebythe latter is adapted torock or tip laterally,suitable springs S (seeFigs. 1 and 2) preventing undue movement of 3 the tipping plate upon itsjournals.

The tipping-plate holder A is mounted on i trunnions a extended throughlongitudinal slots c in the upturned part of the base 0, pivoted at C,Fig. 1, to a carriage D, which is adapted to slide longitudinally on theframe, said base 0 being freely rotatable about its said pivot Oto-enable said base and the parts 5 carried thereby to freely adaptthemselves to the inclination of the end of the last, as will behereinafter described. The rear end of the carriage (see Figs. 1 and 3)is herein shown as provided with a rackibar'd tobe engaged at times by asuitablyshaped tooth 'd on a lever d pivoted to an jeajr a on thetipping-plate holder, whereby j the head of the machine may, whendesired, be manually swung laterally about the pivot '0 and, ifnecessary, held in adjusted position on the carriage. The pivotal pointof the head is shown in alinement with the center of the end of thelast, and by the lateral adjustment of the head the side-wiper plates orwipers (to be described) are adjusted to the varying inclinations of thesides of the last for example, the last in a right or a left boot orshoe. I

- The base G is shown provided with a rearwardly-eXtended-and upturnedhorn C ,Fig.1, slotted at O to receive a stud of on the tipping-plateholder, and by means of an adj ust ing-screw a, connected by aball-and-socket joint to one end of the horn and extended t through athreaded opening in theear a the tipping-plate holder A may be tippedupon its trunnions a to vary the inclination of the tipping plate fromfront to rear.

A toe-rest e of any suitable construction isherein shown as mounted upona slidebar 1 c, Fig. 2, longitudinally movable in a guideway D, forminga part of the carriage and vertically adjustable by means of a cam D ona cam-lever D adapted to rock on a suitable stud by means of ahand-lever D all as in my other application hereinbefore referred to.

The tipping plate B has a raised portion 12 thereon to form a supportfor an actuatingcam F, provided on its under side or face with acam-groove f and in its upper face with two cam-groovesf'f (see Figs. 3and 4,) for a purpose to be described, the said cam being mounted on asuitable stud F, as clearly shown in Fig. 4c.

The tipping plate has adj ustably connected thereto a bracket g, inwhich is mounted an elbow-lever g, pivotally connectd at g to atoe-wiper holder 9 the other end of the lever being connected by aknuckle-joint g to a slide-plate 9 adapted to slide in a recess in thetippingplate B and provided with a suitable roller or other stud g toenter the camgroove f on the actuating-cam.

' The toe-wiper holder isvertically socketed to receive therein theshank 9 Fig. 1, of an end-wi per or clasp carrier, shown as a groovedplate g upon the inner or concaved face of which is secured a pad ofleather or other suitable material, which constitutes one form of wiperor clasp to wipe the upper about the end of the last as the said Wiperor clasp is elevated by the rocking motion of the elbowlever g, thelatter being actuated by a partial rotation of the cam F.

The end wiper or clasp may be free to swing laterally upon its shank gto accommodate itself toa right or a left boot or shoe, its shank gbeing shown as circumferentially grooved, asat g to receive a pin g",held in the socket, and which restrains said shank against endwisemovement without interfering with the rotation thereof, said shank andits socket be- ,able bolts or screws, as 10, Fig. 3.

ing, however, provided with holes 9 into or through which said pin maybe inserted to restrain said shank and its wiper against rotativemovement, and thereby lock the same rigidly to the base and partscarried thereby for automatic adjustment, as will be hereinafterdescribed.

An abutment h, to position the toe of the boot or shoe when placed upontoe-rest e, forms a part of an ab utment-plate h, adapted to slidelongitudinally in a wiper-carrier support 7c, shown as a slide-barmovable longitudinally in the cap G, secured to the tipping plate abovethe actuating-cam by suit- A roller or other stud 71.2 on the under sideof the abutment-plate enters the cam-groove f to be reciprocatedthereby, the shape of the cam-grooves f and f being such that theabutment h is Withdrawn from the toe of the boot or shoe as the toe-wiper g is elevated.

The cap G is recessed upon its under side,

as stated, to form a guide for the slide-bar it, having a roller orother stud It to enter the cam-groove f and longitudinally slotted at kto receive a lug 72. on the abutment, for a purpose to be described.

In the construction herein shown, referring to Figs. 4 and 5,wiper-carriers m are pivoted at m to the under side of the slide-bar k,which herein constitutes one form of wiperactuator, said carrier beingrocked or swung laterally by means of cam-plates at, secured to thewiper-carriers in suitable manner, as by a screw-and-dowel connection atn Fig. 5, the cam-plates extending at opposite sides of and above theslide-bar 7c and having therein slots 02 to be entered by fixed pins orstuds 25 on the under-side of the cap G, whereby as the slide-bar 7c ismoved forward the wipercarriers m will be moved forward and also platesbeing slotted at o concentrically to the said center to receive thereinsuitable adj usting-screws 0 on the carriers, whereby the plates may beadjusted upon their carriers independently one of the other to adaptthem to the particular shape of the boot or shoe which is to be lasted.7

The inclination of the sides of the boot or shoe at or adjacent the toeor heelz'. e., the swingvaries according to whether the shoe is a rightor a left shoe and also according to the particular style of last, andto adapt the apparatus herein described to act upon either a right or aleft boot or shoe or 011 rights or lefts of different styles it isnecessary to laterally adjust the wiper-carriers and the said'wipers orWiper-plates and the last relatively preferably about the center ofmovement m which latter is located in a line drawn along the bottom ofthe last from the center of the toe to the center of the heel thereof,and in this instance of my invention such adjustment is provided for byswinging the entire head of the machine about the pivot G of the 'base0. By means of this lateral adjustment of the wiper-plates I am enabledto cause the latter to approach the sides of the last uniformlythroughout their lengths and to wipe the upper over the last equally,inasmuch as the leading edges of the side-wiper plates can be brought upto the upper to act upon it simultaneously at each side of the toe.

It is obvious that the mechanism shown and described, without.substantial change and without invention, may be employed 'at the heelend of a last tolast the material thereat and likewise be adjustablethereat to meet differences in swing, for with rights and lefts the heelend of. the last varies proportionally as the toe end, and sincesubstantially the same mechanism hereinbefore described is all thatwould be necessary to' accomplish the lasting and adjustment at the heelI have not shown the same.

As in my other application hereinbefore IZC.

referred to I have provided a tack or nail puller claw r to engage atack or nail 50, (see Fig. 3,) driven into the upper at the under sideof the center of the toe, said claw being formed on the end of arocker-arm r, pivoted at r on the cap G, said arm being rockedon itspivot by means of a dog 1*, engaged by the lug h on the abutment-plate hwhen the, latter is moved rearwardly to withdraw the abutment, a pin ron the dog engaging a suitable ear r on the arm r.

To hold the tack or nail puller in raised position when withdrawn, asdescribed, I have provided a spring-catch s on the cap to engage thefoot r of the arm 4".

To prevent the inner sole from being moved rearwardly by thewiper-plates when wiping the upper thereover, I have provided a downholdif, adjustably mounted in a hub 25 on a rocking arm i pivoted at r andacted upon bya spring 8 to normally lift it, the arm having on its underside a locking-ear t to engage a shoulder 7 5 on the cap G and retainthe downhold in place against the action of the spring. The arm isslotted at its pivotal point at 15 to permit longitudinal movementthereof when a lug t on the arm t is engaged by the cam-plates n intheir forward movement to thus withdraw the projection i from theshoulder 75, the action of the spring 8 then lifting the downhold intoinoperative position. A rest t on the cap is located in the path ofmovement of and acts as a limiting-stop for the upturned end i of thearm 25 when moved into inoperative position by the spring.

The actuating-cam F is partially rotated in 7 one or the other directionby .means of a suitable handle F movement thereof in the direction ofthe arrow 100,,Fig. 3, acting by or through the several cam-grooves f ff and the intermediate connections to withdraw the abutment h and movethe toe-wiper or'clasp g to wipe the toe of the upper about the last andalso to actuate the tack or nail holder, while the wiper-plates orwipers are moved. forward and closed to wipe the upper uniformly andwith an equal draft over the sides of the toe of the last. Movement ofthe han-" dle F opposite to the arrow 100 restores the abutment andwiper plates to their original position ready to last another shoe, theoperator moving the tack or nail puller and the downhold into theirposition by hand.

While the base and supported parts of the head may be manually adjustedlaterally on the carriage prior to lasting or even after the partialrotation of the cam, in either of which cases the end clasp g ispreferably left free to swivel in its socket to adapt itself to the toewhen it meets the latter in rising, yet for the most expeditiousoperation of the machine the pin 9 will be inserted in the holes g tolock the clasp g rigidly to the base and parts carried thereby,includingthe side wipers, and the handle-lever d is permitted to remainin its elevated position out of engagea left last, as soon as it israised toward a.

right last the clasp g on meeting the last will automatically adaptitself to the different inclination of the sides or swing of this rightlast and will thereby automatically swing the head to which it isrigidly attached by the pin g into corresponding position, also inproper alinement with this right last, thereby swinging the wipers intoproper position with relation to the sides of the last and accomplishingautomatically what would otherwise be accomplished through the medium ofthe handle-lever d the clasp when pressed tightly against the end of thelast furnishing sufiicient power to swing the necessary partsautomatically into proper position in alinement with the median line ofthe last.

When the machine is set to operate automatically, the end clasp g?fulfils the function of and forms one form of positioning device forautomatically positioning the parts in proper operative positionrelatively to and determined by the last. 7 v

My machine, therefore, iscapable of either automatic or manual operationat the will of the operator, and it is evident that my invention is notto be restricted to the particular construction herein shown anddescribed.

In another application, Serial No. 637,850, filed May 24, 1897, I haveshown different means for obtaining the automatic relative adjustment ofthe lasting devices and last, and in said other application, Serial No.637,850, I have claimed such automatic relative adjustment broadly andgenerically.

In another application, filed May 24, 1897, Serial No. 637,850, I haveshown other mechanisms for accomplishing automatically the right andleft adjustment herein referred to to meet the variations in swingpresented by the ends of lasts, whether rights or lefts, said IIO otherapplication containing generic claims relatively-fixed center, a longitudinally-movable slide -bar supported in the head, and wiper-platesmounted to swing about a common center on said slide-bar, combined withactuating means to move the wiper-plates forward and to close them overthe toe of the last, substantially as described.
